Like tdileo said not all SPS are created equal. The term itself isn't scientific but one we use in the hobby. The ones he mentioned plus cyphastrea (gets labeled SPS sometimes, sometimes LPS) which is an encrusting stoney coral are not very demanding.
I forgot about cyphastrea, good mention. Can grow in really low light and are easy to keep, another fantastic beginner stony coral. I think of them more as LPS than SPS, and those terms only being used in the hobby is very accurate.
